And it went wrong simply by itself. "irq 21: nobody cared!" The only thing I'm sure about is that there is something either with UP IO-APIC support, or with the uhci_hcd module. When both are combined, as you can see, this is completely unstable. One time it works, one time it doesn't. But if I use a kernel compiled without UP IO-APIC, or if I boot an IO-APIC-capable kernel with the "noapic" option, then the problem is gone, and it is stable (really, this time). But of course, I don't have no IO-APIC anymore...
